Simulation compares energy yield in silicon solar cells with laser enhanced contacts to conventional devices, indicating performance varies by defect density and resistivity.
Key Points
High-resistivity wafers improve efficiency at low defect levels, but degrade performance as defect levels rise, especially in laser-enhanced devices.
Energy yield simulations reveal that low-light conditions diminish the advantages of high-resistivity wafers when bulk defects are present.
Devices with laser-enhanced contacts show comparable voltages to heterojunction counterparts, highlighting the technology's effectiveness.
Comprehensive simulation-based analysis informs the impact of bulk defect density and resistivity on silicon solar cell performance.
